@@ 从20世纪60年代开始.钛酸锌(ZnO-TiO_2)体系相图及特性的基础研究工作就开展起来了[1].钙钛矿型氧化物结构的ZnTiO_3及基于ZnTiO_3的一些ABO_3型陶瓷固溶体材料,由于在超导体、催化剂、微波介电陶瓷以及电磁材料等领域有着重要用途,近年来已引起越来越多的关注[2～9].%ZnTiO_3 nanocrystals were prepared by sol-gel method, using Zn(NO_3)_2 and Ti(C_4H_9O)_4 in the topic. The as-prepared ZnTiO_3 nanocrystals were characterized by XRD, FTIR and TEM, and the catalytic performance of ZnTiO_3 nanocrystals of different contents for the ammonium perchlorate (AP)decomposition was investigated by thermal analysis. The results indicate that ZnTiO_3 with pure cube structure can be synthesized at 600 ℃ by this procedure,which was spheroid with particle size of about 60～100 nm. The results expressed that the low temperature decomposition peaks of AP is advanced by 17 ℃ and the high temperature decomposition peaks of AP is advanced by 24 ℃ when adding 5% nanoparticle ZnTiO_3 powder. The catalytic effects of ZnTiO_3 powders on the high temperature decomposition of AP are less than that of nanometer metal powders, but all the micron metal powders decrease the low decomposition temperature of AP.
